It says," use the rectangle. Round to the nearest tenth."

To find the perimeter and the area of the rectangle you must have its length and width
So we will find AB as width and BC as a length
The rule of the distance between two points is
[tex]d=\sqrt[]{(x2-x1)^2+(y2-y1)^2}[/tex]A = (2, 6) and B = (4, 3)
x1 = 2 and x2 = 4
y1 = 6 and y2 = 3
Substitute them in the rule to find AB
[tex]AB=\sqrt[]{(4-2)^2+(3-6)^2}=\sqrt[]{4+9}=\sqrt[]{13}[/tex]B = (4, 3) and C = (10, 6)
x1 = 4 and x2 = 10
y1 = 3 and y2 = 6
[tex]BC=\sqrt[]{(10-4)^2+(6-3)^2}=\sqrt[]{36+9}=\sqrt[]{45}=3\sqrt[]{5}[/tex]The perimeter of the rectangle
[tex]P=2\lbrack\sqrt[]{13}+3\sqrt[]{5}\rbrack=20.6[/tex]The area of the rectangle
[tex]A=\sqrt[]{13}\times3\sqrt[]{5}=24.2[/tex]The perimeter = 20.6 units
The area = 24.2 square units
